OpenVRML is a VRML and X3D browser plug-in and C++ toolkit for incorporating VRML/X3D support into applications. It provides VRML97 and Classic VRML X3D parsers, a runtime, and an OpenGL renderer as C++ libraries. The renderer is fully separate from the runtime library so that users can also provide their own renderer. The OpenVRML browser is provided as a D-Bus service, and is embeddable in host applications using XEmbed. The distribution provides both a stand-alone host and a host that runs as a Mozilla plug-in.

psycopg is a PostgreSQL database adapter for the Python programming language. Its main advantages are that it supports the full Python DBAPI 2.0 and it is thread safe at level 2. It was designed for heavily multi-threaded applications that create and destroy lots of cursors and make a conspicuous number of concurrent INSERTs or UPDATEs. The psycopg distribution includes ZPsycopgDA, a Zope Database Adapter.

GNU Mailutils is a rich and powerful protocol-independent mail framework. It contains a series of useful mail libraries, clients, and servers. These are the primary mail utilities for the GNU system. The central library is capable of handling electronic mail in various mailbox formats and protocols, both local and remote. Specifically, this project contains a POP3 server, an IMAP4 server, and a Sieve mail filter. It also provides a POSIX "mailx" client and a collection of other handy tools.

Common Text Transformation Library is a library of C++
classes and functions to parse and modify STL strings.
CTTL substring classes may be compared, inserted,
replaced, and parsed with EBNF grammars. The compiled
program implements a fast, thread-safe, re-entrant recursive descent parser.

WildMidi is a wave table player that uses Gus Pat sound
sets to play MIDI files. It is capable of multi-threading
and multi-processing of MIDI files, allowing for the mixing
of multiple MIDI files at any one time.

Asymptote is a powerful descriptive 2D and 3D vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. Asymptote is a programming language as opposed to just a graphics program. It can exploit the best features of script (command-driven) and graphical user interface (GUI) methods. High-level graphics commands are implemented in the language itself, allowing them to be easily tailored to specific applications.

Kolab is a groupware system that provides a
comprehensive and flexible solution for
workgroups. Email, contacts, and group calendars
can be managed via the Web, Windows/Outlook, and
Linux/KDE. It supports offline synchronization and
full seamless support of mixed client environments
because the Kolab-XML storage format is fully open
and avoids MAPI/TNEF.

Papyrus is a 2D C++ scenegraph (canvas) library that utilizes the cairo
library to perform drawing operations. Similar canvas libraries are the
Gnome Canvas, Diacanvas, and the QT Canvas. Numerous canvas primitives
are available, including arcs, rectangles, polylines, and line markers.
An optional companion library, Papyrusmm, provides a set of Gtkmm
widgets which includes viewports (a canvas display widget similar to
Gtk::DrawingArea) and other UI widgets related to drawing interfaces.

MUNGE (MUNGE Uid 'N' Gid Emporium) is an
authentication service for creating and validating
credentials. It is designed to be highly scalable
for use in an HPC cluster environment. It allows a
process to authenticate the UID and GID of another
local or remote process within a group of hosts
having common users and groups. These hosts form a
security realm that is defined by a shared
cryptographic key. Clients within this security
realm can create and validate credentials without
the use of root privileges, reserved ports, or
platform-specific methods.

Talend Open Studio for Data Integration is an ETL (Extract, Transform, and Load) tool. Talend Open Studio for Data Integration can perform jobs that range from datawarehouse feeding to database synchronization, as well as file format transformations. Its graphical interface is made with Eclipse RCP, and data related scripts are generated in Perl or Java. The application was designed to be extended with components written by users.
